Hinge for a swash plate

摘要

A variable displacement compressor includes a rotor (17), which is fixed to a drive shaft (16), and a pivotal swash plate (18), which is supported on the drive shaft (16) and slides in an axial direction along the drive shaft (16). A hinge mechanism (20) is located between the rotor (17) and the swash plate (18). The hinge mechanism (20) rotates the swash plate (18) integrally with the rotor (17) and guides the pivoting and the sliding motion of the swash plate (18). The hinge mechanism (20) includes a swing arm (43), which extends from the swash plate (18). The swash plate (18) is made of aluminum or aluminum alloy material. The swing arm (43) is separate from the swash plate (18) and is made of iron-based metal material. Therefore, while the swash plate (18) is light, the hinge mechanism (20) is strong. <IMAGE>
